From 1f520f15a31d41a7f153258de9acd640ff227fc8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beat=20K=C3=BCng?= Date: Thu, 9 Mar 2017 10:16:53 +0100 Subject: [PATCH] px4fmu-v4 NuttX defconfig: lower CONFIG_DEV_PIPE_SIZE to 70 This saves almost 2kb of RAM when using the mavlink shell. 70 matches the size of the mavlink message. Since the pipe is blocking, a process writing a lot of data will just wait, data will not be dropped. The mavlink shell is the only process creating a pipe. --- nuttx-configs/px4fmu-v4/nsh/defconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/nuttx-configs/px4fmu-v4/nsh/defconfig b/nuttx-configs/px4fmu-v4/nsh/defconfig index c838f17b7b..ddc3f0f727 100644 --- a/nuttx-configs/px4fmu-v4/nsh/defconfig +++ b/nuttx-configs/px4fmu-v4/nsh/defconfig @@ -881,7 +881,7 @@ CONFIG_RAMTRON_SETSPEED=y # CONFIG_EEPROM is not set CONFIG_PIPES=y CONFIG_DEV_PIPE_MAXSIZE=1024 -CONFIG_DEV_PIPE_SIZE=1024 +CONFIG_DEV_PIPE_SIZE=70 CONFIG_DEV_FIFO_SIZE=0 # CONFIG_PM is not set # CONFIG_POWER is not set
